Explanation: The explosion is over, but the consequences continue. About eleven thousand years ago, a star in the constellation of Vela could be seen to explode, creating a strange point of light briefly visible to humans living near the beginning of recorded history. The outer layers of the star crashed into the interstellar medium, driving a shock wave that is still visible today. The featured image captures some of that filamentary and gigantic shock in visible light. As gas flies away from the detonated star, it decays and reacts with the interstellar medium, producing light in many different colors and energy bands. Remaining at the center of the Vela Supernova Remnant is a pulsar, a star as dense as nuclear matter that spins around more than ten times in a single second.

a star as dense as nuclear matter

I don't know what that means. A neutron star has the mass between 1.4 and 2x the mass of the sun compacted into a diameter of about 12 miles.

[No name given]

Wow.

[George from New England]

Looks more like something inside our bodies.

So, it's jus' a bunch a gas?

[MtnClimber]

And it spinnin so fast it hard to find the flag the asternots left there..

[Bullish]

Well that genius was the chair of the space committee or some such.

Sometimes the old needs to doe to make room for the new.

Let ‘em die.

Bring on entrepreneurial beer companies to grow.

As dense as an atomic nucleus. A neutron star (i.e. pulsar) is for the most part a giant atomic nucleus weighing more than the sun, and made up of tightly packed neutrons. The exact density varies from surface to core, but generally is about 100 million tons per cc.

So you need a forklift to move one of those around.

[Telepathic Intruder]

If superman is driving.

[Seruzawa]

Sorta looks like what my BIL’s head will look like after Trump wins reelection.

[Reynoldo]

I’ve read that the surface is spinning so fast that the equator is moving about 1/4 the speed of light.

There are videos what Vela sound like converting it’s EM jet to sound.

So, we could probably never live there?

[Telepathic Intruder]

Chuck Norris could live there. No one else.
